This page explains both how to successfully complete ship massacre missions, and the effect on the BGS (Background Simulation). Use the tags above to read about related items, together with similar/related functions in-game.
Massacre missions show 3 ship icons against a target.
Massacres involve killing a set number of ships, either by finding them in Conflict Zones (CZ), Resource Extraction Sites (RES), pulling them out of Supercruise using a Frame Shift Interdictor. Different targets affect different states. Conflict zone ships during war affects the war, and out of war increases lockdown for the target. See the other types of massacre too.
